The Amprobe CO2-200 is a wall-mounted carbon dioxide meter designed for air quality compliance monitoring in critical environment controlled areas such as laboratories and production floors. It provides simultaneous measurement of CO2, temperature, and humidity on a super-large LCD display.

The meter utilizes a low-drift NDIR (Non-Dispersive Infrared) sensor for CO2 measurement from 0 to 9999 ppm with accuracy of ±75 ppm ±5% of reading. Temperature measurement ranges from -10 to 60°C with ±0.6°C accuracy, and humidity from 0 to 95% RH with ±3% accuracy at 25°C. Derived parameters include dew point and wet bulb temperature.

A key feature is the audible alarm with user-configurable threshold that can be set to a specified CO2 level. An output drive relay is included to control ventilation systems automatically based on CO2 concentration. Data hold and Maximum, Minimum, and Average value recording are provided. A USB interface enables downloading of results to a PC for further analysis.

The CO2-200 ships factory calibrated and is suitable for continuous monitoring in commercial and industrial environments requiring air quality verification.
